摘要：
An enhanced water-absorbency hydrophilic polymer material, suitable for use in for example would dressings, is prepared by a process in which a water-containing organic hydrogel comprising a gelable polysaccharide and/or protein or polypeptide interpersed with a polymer of a hydrophilic acrylic or methacrylic acid derivative is permeated with a base, the pH of said hydrogel being raised to at least 9 during treatment with said base.
